SANTA CRUZ -- Deputies identified Bradley Gordon Dreher as the 47-year-old man who was found dead in Santa Cruz County Jail on Sunday.

Dreher was found hanging in his cell about 11:20 a.m., Sgt. Patrick Dimick said.

Deputies said Monday that they collected evidence for a routine investigation of the death, which appeared to be suicide. Dreher listed his occupation as an iron worker and was living in Soquel, authorities said.

He had been arrested about 8 p.m. Friday on suspicion of making criminal threats on North Rodeo Gulch Road in Soquel, according to arrest records.

He was housed in a single cell because he said he had trouble getting along with other inmates, Lt. Fred Plageman said. Dreher did not seem depressed, deputies said.

About 5 a.m. Sunday, Dreher received a medication from a nurse and later breakfast. He appeared alert and didn't show any suspicious behavior during a correctional officer's check about 10 a.m., deputies said.

When he was found not breathing and alone in his cell, jail medical staff and emergency responders tried to resuscitate him. He was declared dead about 11:40 a.m.

Deputies initially said he was 41 years old.

Dreher's death is the fourth in County Jail since August and the first apparent suicide among those deaths, authorities said.

A 27-year-old woman died from medical problems related to injection drug use in August. In October, a 59-year-old man died from cardiac problems during booking for a DUI, and in November a 47-year-old man died. He was detoxifying from drug use.
